The process of downloading the Arima LH520 BIOS 1.13 driver should begin automatically after a few seconds. If this does not occur, click on one of the links below (we recommend downloading the Arima LH520 BIOS 1.13 driver from the primary server - this is the manufacturer’s Arima official website). If the download still fails to run, check whether your anti-virus software is not blocking the connection to the manufacturer server of the Arima LH520 BIOS 1.13 diver.
